Vacuum preloading drainage system and foundation treatment method
The invention provides a vacuum preloading drainage system and a foundation treatment method. The vacuum preloading drainage system comprises a plurality of pipeless dewatering wells arranged in a stratum, an airtight film which is arranged on the ground surface and covers the multiple pipeless dewatering wells, and an air compressor, the air pipe system is connected with the air compressor and the plurality of pipeless dewatering wells, the water pipe system is connected with the plurality of pipeless dewatering wells and drains water outwards, each pipeless dewatering well comprises a well head arranged in a well hole, a water pumping pipe and an air pipe, and the water pumping pipe and the air pipe are respectively connected with the well head. The well head comprises a water filtering bin and a water-air bin arranged below the water filtering bin, the water filtering bin and the water-air bin are communicated through a one-way valve, one end of the water pumping pipe is arranged at the bottom of the water-air bin, the other end of the water pumping pipe is communicated with the water pipe system, one end of the air pipe is arranged at the top of the water-air bin, and the other end of the air pipe is communicated with the water pipe system. And the other end is communicated with the air pipe system. The technical scheme of the invention has the advantage of high drainage efficiency.
